In this way, the occurrence of the additional antenna required to be arranged separately for receiving the first diversity reception signal and the second diversity reception signal may be reduced. The number of the antennas may be reduced, such that the problem of the difficulty of arranging the antennas in the electronic devices resulting from more antennas in the electronic devices may be solved at least to a certain extent. As a result, the spaces of the electronic devices may be saved effectively. In addition, the number of the RF channels may be reduced by virtue of adopting the triplexers, such that the space of the motherboard may be saved.
